The rebound came after the markets had their worst day Monday since the 2008 financial collapse: the Dow lost 5.6 percent, the S&P 500 6.7 percent, and the Nasdaq 6.9 percent. The surge came in the last hour, with the Dow 150 points in negative territory 45 minutes before the close.It followed an announcement by the Federal Reserve that it expected to maintain interest rates at ultra-low levels for the next two years due to economic weakness.

On the Nasdaq, eBay jumped 11.6 percent, Yahoo 8.75 percent, and Apple 5.6 percent. Already at two-year lows, US bond yields plunged after the Fed's announcement.
